Wash the golden potatoes thoroughly and cut them into equal parts.
Place the cut potatoes into a large pot and fill it with water until the potatoes are covered. Add 1 tsp of salt to the water.
Bring the pot to a simmer over medium heat and cook the potatoes for about 20 minutes or until they are fork-tender.
Once the potatoes are cooked, strain them, and return them to the pot or transfer them to a large bowl.
To the cooked potatoes, add the butter, sour cream, ranch seasoning, ½ tsp salt, ½ tsp pepper, and ½ tsp garlic powder.
Using a hand mixer, whip the potatoes until smooth and creamy. If the mashed potatoes are too thick, add a small amount of milk or heavy cream to achieve your desired consistency.
Taste the mashed potatoes and adjust the seasoning, if necessary, by adding more salt, pepper, or garlic powder according to your preference.
Serve the Garlic Ranch Mashed Potatoes hot as a delicious side dish.
Enjoy your flavorful Garlic Ranch Mashed Potatoes!
